Good. Maybe I have it set right finally! I showed 4.2, but the map from park had me second guessing it. I will leave it for now. Thanks all

There's a nice strava segment for North Tower Loop that reports 4.2 miles.

That is a really fun circuit.

I switched from Spinergy wheels to Stan's Notube Arch 29er rims and all I can say is wow!

Night and day for mounting and sealing tires.

If I was focusing on a single trail system I might. But i am working on lots and don't have the time to walk everything. I usually ride the trail a few times and then hand draw the files I actually upload to mtbproject.  Right now I have some very high quality trail data from the dnr that WAS walked (and I think with survey grade gps hardware to boot-the point density is insane) so I mostly focus on photos and written descriptions now. And the trails on my plate now are further from home and take more work to list.

Interesting info Nate.


So you walk the trails you map for the MTB Project?

What was the logic behind that reroute?

Don't make me use the "F" word.

Huf was never happy with that line once we picked counter-clockwise as the riding direction.  Like most sections at Fort Harrison, the original plan was to ride that section the other direction, and that corner was pretty decent as a Left, but not so much as a Right.  He tried adjusting the approach with a berm (the "B" word!), but there really wasn't enough room to make it right.  So we took it down and out, thereby straightening out the approach to the trees.  I think it rides pretty nice.

Don't be surprised if you see more reroutes coming to Ft H soon.  Change is not a bad thing!

Don't worry about Huf. He also thinks that any tight singletrack needs to have all the trees cut out that do not fit his 6ft wide handlebars (i.e. Bobcat Bowl)

I plan to start making more Wednesday workdays since my evenings have been freed up recently.


I need to get my Rogue Hoe fixed, though.  I broke it at SWW this spring and haven't had a chance to find someone who can weld it back together.

It is over 4 miles in length, just a hair short of Green Valley.  They are very close, but GV is longer.


Tree cover has very little to do with under-reporting of GPS distance measurements.  It has to do with the curviness of the trail and recording interval of the GPS.  It is not being fooled.  It simply is that the recording interval is insufficient to capture the complete corner.  The shorter the recording interval, the worse it is.  Also, GPS does not capture the tangent of a slope when ascending or descending.  It is simply measuring the horizontal distance.  You can do calculations later to generate the tangent of a slope, but the GPS does not do them on its own.


To capture a trail's distance the most accurately with a gps, you need a VERY high frequency and you need to be walking so your tracks have a very high point density.


1Hz is usually the best you can get on most devices.  If you're riding, that can still give you a pretty good distance between points when going downhill.  At slower speeds, it will be more accurate.  Until we see recording intervals approaching 10Hz or 100Hz on consumer gear, GPS will be significantly short.

Avon - Washington Township Park / Re: Avon Trail Work
« Last post by getsometrail on October 24, 2014, 01:37:10 PM »
My experience with the Avon trails is that they were very confusing and sometimes unusually difficult to ride.  The trails had many unmarked intersections, a lot of which were unofficially made, and hardly any flow whatsoever.  Flat sections would turn sharply into a nearly impossible climb and you could go from difficult trail to really easy without even knowing.  I'm sure folks would ride there if the trail system were better designed.  I really think it would need a big overhaul, planning, and some capitol.  The terrain is nice and has some potential but in my opinion needs a master plan so the bad trails can be reclaimed and the good ones connected in a way that makes the ride more flow better.  This is kind of the same thing that is being done at Southwest Way. 
Unfortunately like bbeohman I have 4 kids and a demanding schedule.  I don't have the time or experience to lead such a project.  If I remember correctly this is not an official HMBA trail either so like RNP, Wapehani, or Muscatatuck the trail work needs to be organized with Washington Township Parks independent of the HMBA.
